Outfielder Matt Joyce was placed on the 15-day disabled list with a left external oblique strain.
Right-hander Joel Peralta dropped his appeal and immediately began serving his eight-game suspension for using a foreign substance on his glove.
Infielder Brooks Conrad reported to the team after being claimed off waivers Thursday from Milwaukee.
Right-hander Brandon Gomes was recalled from Triple-A Durham, a move that would not have been possible unless the Rays had an injury. Gomes was sent back to Durham after Sunday's game and had there not been an injury, he would have had to wait 10 days before he could be recalled.
Outfielder Rich Thompson was optioned to Durham.
Infielder Drew Sutton was designated for assignment.
"Obviously [Friday's moves] have been a couple of days in the making," said Rays executive vice president of baseball operations Andrew Friedman. "We knew what we likely faced with Peralta and weren't really sure on Joyce.
"... Last night we went through it in detail and kind of had a chain of events in order and went through different checkpoints, and once we knew that Matt Joyce was going to go on the DL, we used that to activate Brandon Gomes, because we would not have been able to otherwise."
The Rays made moves involving 10 players on May 9, 2003, when they added infielders Felix Escalona and Antonio Perez, outfielder Jason Tyner, and left-handers John Rocker and Jim Parque. Subtracted that day were shortstop Rey Ordoñez, right-handers Steve Parris and Victor Zambrano, outfielder George Lombard and third baseman Chris Truby.
